UNE 23033/81 regulations, which sets standard measurements for fire safety signs, state that use of safety pictograms is compulsory and any text is optional. However, the use of signs with text is common due to the explanations provided by the text.
For securing signs to various supports, such as walls, it is recommended to use double-sided adhesive tapes or neutral silicone. Depending on the nature of the support, they can also be secured with screws.
According to UNE 23035/03 regulations, Class B products have less luminescence than Class A products and must be used for signs in any establishment. Class A products have higher luminescence than Class B products and are of preferred use for signs and markings in busy public areas or areas only lit by artificial lighting.
In the case of Escape routes signs:
- Signs indicating evacuation routes should be installed so that at least one sign is visible from any location possibly occupied by people, enabling them to start or continue an evacuation process without doubts or confusion.
- It is recommended that the height of the lower edge of these signs is positioned between 2 and 2.5 metres above the ground. Under no circumstances should they be positioned less than 0.3 metres from the ceiling.
In the case of Fire safety equipment signs:
- It is recommended that the fire extinguisher pictogram sign is positioned between 2 and 2.5 metres above the ground. Under no circumstances should it be positioned less than 0.3 metres from the ceiling.
- All other fire alarm and safety equipment must also be signed (respecting the observation distances and minimum heights to guarantee visibility).
Although regulations do not provide for the use of photoluminescent signs outdoors, there is no problem in using them in outdoor locations.
The Spanish Technical Building Code (CTE) and UNE regulations currently in force provide safety sign measurements based on Observation Distance (OD).
